How does the E-1 handle the problem of dust associated with the use of interchangeable lenses?
Olympus’ patented new Supersonic Wave FilterTM protects the imager from the common problem of micro dust created by the shutter and from the environment. Located between the shutter and the CCD, the Supersonic Wave Filter uses high-speed ultrasonic vibration to cause most types of dust to simply fall away to be collected and held, preventing it from damaging the photograph. For large dust (fluff dust, strings, etc.) and liquid (water drops, rain), the Supersonic Wave Filter may not effectively work, and Olympus recommends the E-1 should be sent to an authorized Olympus Digital Service Center to be cleaned.
